This is the first official declaration from Google that the Google Assistant is on its way out, but it’s not like we weren’t expecting it. Gemini is already the default experience on most mainstream Android devices,

Google's officially retiring its Assistant tool, instead migrating users to its AI-powered Gemini.

Gemini won’t access your search history for every query. It will only do so if it thinks that it will be helpful. It most likely won’t access it if you’re asking a general question. However, if you’re looking for a vacation spot or for fashion advice, then it’ll most likely thumb through your searches.
